Influence of Voltage |
Overload: Operating value ±5%, operating time ±10%, Phase loss: Operating value ±5%, operating time ±10%, Reverse phase: Operating value ±5%, operating time ±10% |
Rated Working Voltage |
Motor circuit: AC200/220V, 400/440V, Output contact circuit: (contact 1a) AC120V/2A, AC240V/1A, AC440V/0.5A, DC110V/0.2A, DC220V/0.1A, (contact 1b) AC120V/5A, AC240V/2A, AC440V/1A, DC110V/0.2 A, DC220V/0.1A |
Allowable Fluctuation of Voltage |
(Control power circuit) 85 to 110% of the rated operating voltage. However, in the event of a phase loss, it must operate normally at 50% of the rated operating voltage. |

Specifications |
●Test button operation (overload elements only): Operating time → time setting value, operating time setting characteristics, ±30%●Effect of waveform distortion: No malfunction with 100% content of each of the second to ninth harmonics (phase loss switch "low")●Phase loss: Operating value → 85% or less of current setting value (in a state of complete phase loss of one phase), operating time → 2s or less at current setting value (in a state of complete phase loss of one phase)●Reverse phase: Operating value → 50% or less of current setting value, operating time → 1s or less●Unbalance: Operating value → Maximum current phase is 85% or less of current setting value, operating unbalance rate: "high" 35±10% (25 to 45%), "low" 60% or more, unbalance rate = reverse phase/positive phase |
Insulation Resistance (MOhm) |
10 or more (between the live terminal and the mounting panel), 5 or more (between live terminals, between contact poles) |
Rated Frequency (Hz) |
